    copied!<p>You may have notice that later versions of gcc is more strict with standards (<a href="https://stackoverflow.com/questions/605497/accessing-inherited-variable-from-templated-parent-class">see this question</a>)</p> <p>All inherited members of a template class should be called using the full name, ie. <code>ParentClass&lt;T&gt;::member</code> instead of just <code>member</code></p> <p>But still I have a lot of old code that does not respect this. Adding <code>using ParentClass&lt;T&gt;::member</code> for each used member in each class is quite a pain. Is there is a way to do something like <code>using ParentClass&lt;T&gt;::*</code> ?. I would like this better than deactivating this check in g++ but if there is now way, how can I deactivate it ? </p> <p><strong>Edit</strong>:</p> <p>According to C++ FAQ (thanks sth) these are the only way to correctly solve the inherited member variable names : </p> <ol> <li><p>Change the call from <code>f()</code> to <code>this-&gt;f()</code>. Since this is always implicitly dependent in a template, <code>this-&gt;f</code> is dependent and the lookup is therefore deferred until the template is actually instantiated, at which point all base classes are considered.</p></li> <li><p>Insert <code>using B&lt;T&gt;::f</code>; just prior to calling <code>f()</code>.</p></li> <li><p>Change the call from f() to <code>B&lt;T&gt;::f()</code>. </p></li> </ol> <p>So now looking for the right switch to deactivate the full name resolution ...</p>
